MUSICAL IN SPECIFICATION forming part of Letters Patent No. 740,514, datedOctober 6, 1903.

To (LZZ whom it may concern: 4

Be it known that I, ROBERT J. BENNETT, a citizen of the United States, residing at Chi? 'cago, in the county of Cook and State of Illi- 5 nois, have invented a certain new and useful Improvement in Musical Instruments, of which the following is a specification.

My invention relates to wind instruments whose sound-producing mechanism is capable of being actuated in either of the following waysto wit, by the manipulation of keys alone or in combination with stop-rods, by a traveling music-sheet alone or in combination with stop-rods, manually or mechanically consecutively and alone or in combination with stop-rods, manually and mechanically simultaneously and alone or in combination with stop-rods; and it also relates to means whereby the tones produced by the operation of the parts of the said instrument in either of the ways mentioned will be of a superior quality and the disagreeable noises usually incident to such instruments reduced to a minimum; and it further relates to means whereby a Variety of tones or combinations of tones may be produced from one and the Heretot'ore musical instruments operable in either of the manners referred to have been so constructed that though the fundamental tones prod uced therefrom have been of the necessary pitch, yet by the interruption or distortion of the overtones the general result has been the production of tones of more or less metallic, harsh, and disagreeable quality or timbre. Again, the construction has been such as in the operation of the parts of such instruments to occasion a varying amount of noise, unpleasantly interfering with the musical character of the instrument. Further, though secondary reed cells or passages have been used in connection with direct reed cells or passages to convey air to one and the same reed for the purpose of producing more than one tone or combination of tones therefrom, yet these secondary cells orpassages have been so positioned in relation to their respective reeds that the effect produced has in a great measure been ofa harsh unmusical character.

The object of my invention is to remedy these defects, and to that end it consists,

broadly, in combining the various elements of a musical instrument, substantially as hereinafter described, whereby the tones produced therefrom in either manner heretofore referred to are of a full, rich, and mellow quality; secondly, in combining my novel pneumatics with a case or cases removable or fixed adapted to receive the same and to muffie any unpleasant noises that may be caused by the operation of said pneumatics; thirdly, in combining a reed section or block removable or fixed with one or more reed cells or passages communicating with each reed in such manner that either a single tone or one of several possible single tones or one of several possible combinations of tones may be produced.

As the device or devices for mechanically or manually controlling the transmission of air to the hereinafter-to-be-described pneulnatics (which pneumatics actuate their respective reeds) may be of any well-known or desired character, it is deemed unnecessary to specifically describe herein any one particular construction. I shall therefore confine my description to those features of construction and operation to which myim provement chiefly relates.

In the accompanying drawings, A is one of a series of intake tubes, pipes, or passages through which air is induced and transmitted to its respective chamber B, (either by mechanical or manual operation of the parts referred to in the preceding paragraph, but omitted from this description.) The chamber, passage, tube, pipe, or duct 0 is subject when the instrument is being operated to a continual suction occasioned by the exhaustion of the air therein contained through the pipe, tube, port, or passage 0 by means of a bellows or several bellows, and the pneumatic D is also subject to the same suction by the exhaustion of the air therein contained through the passage or port d into said passage O, where it mingles with the air therein and is drawn through the port 0 into the wind trunk or duct E, thence into the wind box, chamber, or duct F, and finally to the bellows and there discharged.

Thev collapsible pneumatic D is provided with an aperture or port d (smaller than the apertures in the tracker board or boards,) through which air contained in the chamber B may be exhausted by means of the suction above described. When, therefore, the intake-tube A is closed or idle, the suction upon the upper and the under side of the base of the pneumatic D is equalized and the pneumatic remains in its normal or distended position. \Vhen, however, the intake-tube A admits air to the chamber B, as the influx is greater than the exhaust through the port cl the atmospheric pressure exerted from beneat'h the base of the collapsible pneumatic D raises the base thereof, thereby collapsing the pneumatic upward. When the supply of air from the intake-tubeA is cut 0E, the pneumatic by means of its own gravity resumes its normal or distended position.

G is a two-seat double valve, the stem of which at its lower end connects through part d with the movable side of pneumatic D and rises therefrom through the vertically-overlying ports g and g, which connect the airpassageI respectively with the suction-chamber O and the muffiing-box H, the valve-seats on said stem being so disposed as to coact with these latter two ports. When the pneumatic D is collapsed, it raises the two-seat double valve G, simultaneously closing the port g and opening the port 9 the parts described assuming the relation shown in Fig. II. In this position of the two-seat double valve G air is admitted from the muffling-box H to the tube or passage I through the port g or more apertures h, which communicate directly with the atmosphere, but are made Said muffling-box is provided with one 1 lows.

sufiiciently small to prevent the egress of the" ports j j j to the respective chambers L M N.

While these chambers are thus filled with air, the air contained in the pneumatics 0 0 0 is continuallyexhausted through the respective ports 0 0 0 into the chamber P, whence it is exhausted by the bellows which draws it or draw it through the passages Q into the resonator or resonators R, and thence into and through the wind-trunk E and the wind-.

box F, (see Figs. II, III, and IV,) while the air contained in the pneumatic O is exhausted through the port p into the passage P and conveyed to the wind-trunk E, thence into wind-box, and finally discharged from the bel- By thus collapsing the pneumatic 0 said pneumatic raises the pin S and the valve or pallets. The air from the chamber T now passes into the reed box or cell U, and thence through the reed it into the passage '0, whence it is exhausted by the bellows when the valve 4; is open, thereby producing a tone. These pneumatics O are gravity-pneumatics and beingprovided with small apertures s are opened or distended in the same manner as are the pneumatics D when the influx of air to the chamber K is cut off by the closing of the valve 9 Air is supplied to the chamber T by means of a continuously open port or passage 25 and a port or ports 2?, controlled by a valve or valves i The valves Vand 25 may be controlled by a stop-rod or stop-rods adapted to open them simultaneously or to open valveValone. (SeeFig. XII.) Openingthe port 1?, which directly communicates with the atmosphere, causes a greater influx of air to the chamber T, thereby producing a tone of greater volume than that produced when the intake-port t is used alone.

The operation of the several series of pneumatics 0 0 0 may be adequately explained by a description of the operation of any one of the same-for example, one of the series of pneumatics 0 The inner ends of the suction-chambers P abut against the lower ends of the pneumatic-inclosing chambers L M N, dam, and the resonating passages from the reed-cells Y open into said suction-chambers overhead adjacent to this point and the passages from the reed-cells Y open therein somewhat farther to the front. Pallets X are hingedinside of the chambers Pat the overhead point w near theouter ends thereof, with their free ends reaching nearly to the partition separating the suction chamber from the adjacent pneu matic-inclosin g chamber L, M, or N and are pressed upward by springs 00 to normally close the resonating passages. The pneu matics 0 0 &c., are arranged in their-respective inclosing chambers with apex downward and extending below the plane of the corresponding pallet X. That side-of each pneumatic adjacent to the suction-chamber P may be considered stationary or fixed and the side away therefrom as movable. A port or passage 0 0 &c., opens from the pneumatic through the fixed side and near the apex into the suction-chamber slightly beneath the free end of the pallet therein, and a finger or pin WV, rigidly secured to the movable side of the pneumatic opposite the port,- projects through said port and engages the pallet, as by a yoke on the end of the latter, as shown. Owing to its position near the apex of a hinged leaf or side of the pneumatic, with which leaf it moves rigidly, this finger will act with all the leverage of said leaf upon the pallet when the pneumatic is collapsed to open the latter. Its movement thereagainst will resemble that of a cam, and, in fact, it will have acam action, for which reason it is indicated in Fig. VIII as beveled on the under side of the contacting end, and is hereinafter termed a cam. The opening of the pallet X by the collapse of the pneumatic and cam action of the finger W results in the opening of the resonating passages leading to the .reed cells or passages Y Y and the subpassages, (if

the latter be presentin the reed-section operated,) and by raising a mute air is admitted to a passage thus opened and the reed controlled by said mute is sounded. The bevelended pin W is termed a cam, for the reason that it has a cam-like or sliding engagement with the foot w on the pallet. In other words, these two members, which have a sliding contact with each other, constitute engaging cam members for effecting the opening and closing of the valve. In this way the power-pneumatic is enabled to more easily and quickly open the valve, and, in addition, the spring of the valve is rendered capable of more easily and quickly closing the valve and returning the pneumatic to its normal position. This it will be readily understood is for the reason that a sliding or cam-like engagement is more powerful than a positive connection and a direct thrust.

Any one or all of any set or sets of reeds may be sounded simultaneously or consecutively in the manner described by raising the corresponding mute or mutes by means of any suitable device. When the influx of air to the chambers L M N is out 05 by the closing of the port g, the springs 40 raise their respective valves or pallets X, which in turn distend their respective pneumatics by means of their respective pins or cams .W. As the closing of port g is attended with the opening of port g the air in chambers L M N, &c., will at this moment be exhausted through ports f, &c., passage J, port 2', passage 1, port g3, chamber 0, and port 0, thus relieving the pneumatics 0 0 &c., from eternal pressure and facilitating their distension and inflation with air from chambers P before the pallets X are entirely closed. There will also be suction in the chamber K at this time sufficient to insure thedistension of pneumatic O therein. The pneumatics O o 0 being connected with the passages J j act approximately in unison; but the sounding of any particular reed or reeds depends upon the raising of the particular mute or otherwise opening the particular passage governing the influx of air to the said reed or reeds.

Referring to the enlarged detail of my improved two-seat double valve G, (see Fig. X1II,) 8 is a threaded rod or pin; 9, a leather nut; 10, a spongy substance, such as undressed kid; 11, a hard substance, such as Wood; 12, a kid or other suitable valve-facing. The parts 9 1O 11 12 in each valve 0perated by the rod 8 are respectively glued together. 13 is a leather button; 14, a spongy substance similar to that described above. 13 and 14 are glued together. The upper and lower valves may be positioned at any desired point on the pin 8 by means of the nuts 10, thus controlling the length of movement of the base of the pneumatic Dand assuring a perfectly air-tight closing of the port g or g when its respective valve is seated thereover, a sufficiently-large aperture being made at the points 15 to give the pin 8 freedom to slightly incline in such direction as may be caused by the upward or downward movement of the base of the pneumatic D. When the pin or the base of the pneumatic shall incline, the springy substance will conform to such inclination, thus counteracting the same. It is not to be understood, however, that for the purpose of the broad claims herein contained I confine myself to this or to any particular construction of the two-seat double valve G or of any other details of the structure.

Referring to Fig. II of the accompanying drawings, it will be seen that below the plane of the reed, situated in the cell or passage Y, but connected to such passage, is a secondary or sub passage g, which is controlled by a separate mute. This subpassage, it will be 0bserved, opens into the direct passage Y in advance of the reed, so that the currents in both are directed to the same side of the reed. Repeated experiments attended by considerable expense have taught me that the secondary passages produce a defective tone if located above the plane of the reed and that superior tones can be obtained by locating the secondary passages below the said plane. Opening the upper passage Y alone produces one tone from the reed contained therein, while opening the subpassage 1 alone produces the same fundamental tone, but of a vastly different quality, occasioned by the difference between the overtones of the same fundamental tone. A third difference in quality of tone is obtained by opening both the mute to the upper and the mute to the sub passage. This isflue to amingling of the two qualities of overtones.

By varying the size and shape of the subpassages (for more than one may be employed in connection with a single reed) ditferent qualities of overtones are obtained just as varying mouths emitting tones singly or simultaneously produce. varying qualities of overtones, though each should produce a fundamental of the same pitch.

I do not mean to confine myself to the use of any particular number of subpassages nor to limit their use to one particular set or series of reeds. Again, I do not mean to limit myself to any particular size of the parts of my invention as herein described, and where I have used a descriptive word in a singular sense if the function of that particular part can as well be accomplished by the substitution of a number of similar parts, or, vice versa, where I have used such a word in the plural sense, while the same result might be obtained through the employment of but one of such parts, it is to be understood that my invention is deemed to cover both constructions.

The remarks above being borne in mind a few details may be given respecting a preferred construction of some of the parts of the instrument to which my improvement relates. The resonators R extend the entire length of the instrument. The suction-chambers P and C and the mufliling-box H extend the entire length of the reed-sections. The chamber T and the suction-chamber 7), respectively,extend the entire length of the subbass reed-cells and the subbass-box. There are as many channels J, chambers L M N, pneumatics o 0 0, reeds, and passages-Y Y as there are keys, as many subpassages y as desired, and as many channels j, chambers K pneumatics O of the subbass as there are reeds therein.
